In this video we have the introduction to oscillations. We talk about what it exactly is, the difference between free and forced oscillations, period T and frequency of an oscillation, the Amplitude and Phase difference of an oscillation and how to derive them all from a sinusoidal displacement-time graph for an oscillation.
How to use a stroboscope is also explained for oscillations higher than 6Hz. The Motion of an oscillation is also explained: acceleration, maximum velocity, deceleration, instantaneous rest, changing direction and acceleration again.
The equation for the maximum position is also explained.
This is the first video of the Oscillations, A Level Physics series.
